TheHawke writes: "The Obama administration on Wednesday will unveil its much-delayed general plans for its rocket design, called the Space Launch System, which will cost about $35 billion, according to senior administration sources and information obtained by The Associated Press. It will carry astronauts in a capsule on top and start test launching in six years.

The design for NASA's newest behemoth of a rocket harkens back to the giant workhorse liquid rockets that propelled men to the moon. But this time the destinations will be much farther and the rocket even more powerful.
